Description

Lamp system

Technical Field

The present invention relates to a luminaire system.

Background

A Head Up Display (HUD) is being mounted on a vehicle to Display information for driving assistance. The HUD displays limited speed, information linked to a car navigation system, information of the own vehicle, and the like. Since the HUD is positioned in front of the driver's sight line, the distance over which the driver's sight line moves can be shortened, and safety can be improved.

Further, a lamp is proposed which draws a figure or a character on a road surface and presents various information to a driver or surrounding traffic participants.

Disclosure of Invention

[ problems to be solved by the invention ]

1. The position of the image displayed on the HUD is closer to the front than an object (vehicle, pedestrian, sign) in front of the vehicle. Therefore, the driver needs to move the focus to look at the HUD during driving. Therefore, the driver may not notice the display of the HUD at times.

One aspect of the invention has been made under such circumstances, and an exemplary object thereof is to provide a lamp system capable of reliably transmitting information to a driver.

2. When the HUD and the road surface drawing are performed simultaneously, it is difficult to accurately transmit information to the driver if they overlap when viewed from the driver.

[ means for solving the problems ]

1. One aspect of the present invention relates to a lamp system mounted on a vehicle including a head-up display. The lamp system includes: a light distribution variable lamp for irradiating a light beam with variable intensity distribution to a road surface to draw a pattern; and a controller that controls the light distribution variable lamp in cooperation with the head-up display.

The road surface has a shorter moving distance of the line of sight and a smaller movement of the focus compared to the head-up display. According to this aspect, by making the head-up display cooperate with the road surface drawing, it is possible to reliably transmit information to the driver, as compared with the case where they display and draw independently.

The controller may draw the pattern when it is estimated that the information displayed on the head-up display is not transmitted to the driver or is ignored. By drawing the cooperative pattern on the road surface only in an important scene, the attention of the pattern drawn on the road surface can be enhanced.

The pattern may also include information that emphasizes information displayed on the heads-up display and/or warnings related to the information displayed on the heads-up display.

When the head-up display displays the speed limit, the controller may cause the pattern to be displayed in a blinking manner on the road surface if the actual vehicle speed deviates from the speed limit by more than an allowable amount. The pattern may also represent a limit speed. The speed limit may be alternately displayed in a non-inverted state and an inverted state on the head-up display.

The controller may draw a pattern at a position not overlapping with the display area of the head-up display when viewed from the driver. The drawing position of the pattern may be set individually for each driver.

2. One aspect of the present invention relates to a lighting system mounted on a vehicle including a head-up display (HUD). The lamp system includes: a light distribution variable lamp for irradiating a light beam with variable intensity distribution to a road surface to draw a pattern; and a controller that controls the light distribution variable lamp. The drawing position to the road surface can be set for each driver.

The position of the viewpoint differs for each driver because of differences in height (sitting height), position of the seat, and the like. Therefore, by allowing the driver to set the drawing position according to his or her preference, it is possible to prevent the HUD from overlapping with the road surface drawing and to accurately transmit information to the driver.

The patterns may also include a 1 st pattern reflecting the setting of each driver and a 2 nd pattern not reflecting the setting. If all the patterns are moved uniformly, it is difficult for the driver to see a certain pattern, or the pattern may be presented in a state of being inappropriate for the surrounding traffic participants. Therefore, by classifying the patterns into a pattern that reflects the setting of the driver and a pattern that does not reflect the setting of the driver, it is possible to achieve both the visibility of the driver and the visibility of the surrounding traffic participants.

The 1 st pattern may also include the 1 st information that should be presented to the driver. The 2 nd pattern may also include the 2 nd information that should be prompted to the surrounding traffic participants.

When the display of the HUD is off, the setting of each driver may not be reflected. When the HUD is off, since there is no overlap between the HUD and the road surface drawing, the visibility of the driver to the pattern on the road surface can be improved by invalidating the position adjustment of the pattern.

The setting of the drawing position may be obtained by the driver moving the reference pattern while the reference pattern is drawn on the road surface while the image is displayed on the head-up display when the vehicle is stopped. This enables setting of the position of the road surface drawing without overlapping the head-up display.

Any combination of the above-described constituent elements and a mode of converting the expression of the present invention between a method, an apparatus, a system, and the like are also effective as modes of the present invention.

[ Effect of the invention ]

According to the present invention, information can be reliably transmitted to the driver.

Detailed Description

The present invention will be described below based on an appropriate embodiment with reference to the drawings. The embodiments are not intended to limit the invention but to exemplify it, and all the features and combinations thereof described in the embodiments are not necessarily essential contents of the invention. The same or equivalent constituent elements, members, and processes shown in the respective drawings are denoted by the same reference numerals, and overlapping descriptions are appropriately omitted.

Fig. 1 is a block diagram of a lamp system (or a vehicle lamp) 100 of the embodiment. The lamp system 100 is mounted on a vehicle 200 provided with a Head Up Display (HUD) system 210.

The HUD system 210 presents information for driving assistance to the driver. Examples of the information include (i) external information to be followed by the vehicle, (ii) information linked to a car navigation system, and (iii) information of the own vehicle, but are not limited thereto. (i) The external information includes a speed limit, a vehicle entrance prohibition, a temporary stop, and the like, and may be acquired by imaging a road sign with a camera or may be acquired from a car navigation system. (ii) The information linked to the car navigation system includes a route, a name of an intersection to be turned, a distance to the intersection, and the like. (iii) The information of the vehicle includes a vehicle speed, an engine speed, a remaining amount of fuel, and various warnings of the vehicle.

The HUD system 210 includes a HUD (display body) 212 and its controller 214. The controller 214 causes the HUD212 to display appropriate information according to the driving scenario.

The luminaire system 100 comprises: low beam 102, high beam 104, light distribution variable lamp 110 and controller 130. All of them may be built in the same housing, or several members may be provided outside the housing, in other words, on the vehicle side.

In the present embodiment, the light distribution variable lamp 110 is provided in addition to the low beam 102 and the high beam 104. Therefore, the light distribution variable lamp 110 may be referred to as an additional beam.

The light distribution variable lamp 110 includes a white light source, and receives a control signal S indicating a pattern PTN from the controller 130_CTRLA light beam BM having an intensity distribution corresponding to the pattern PTN is irradiated onto the road surface 900, and a control signal S is formed in front of the vehicle_CTRLCorresponding illuminance distribution (pattern PTN). The configuration of the light distribution variable lamp 110 is not particularly limited, and may include, for example, a semiconductor light source such as an LD (laser diode) or an LED (light emitting diode), and a lighting circuit that drives and lights the semiconductor light source. The light distribution variable lamp 110 may include a matrix-type patterning Device such as a DMD (Digital micromirror Device) or a liquid crystal Device in order to form an illuminance distribution corresponding to the light distribution pattern PTN. Alternatively, the light distribution variable lamp 110 may be an array of light emitting elements (also referred to as μ -LEDs).

The irradiation area of the light distribution variable lamp 110 is determined to cover at least the road surface 900. Therefore, the irradiation region of the light distribution variable lamp 110 may partially overlap the irradiation region of the low beam.

The controller 130 controls the light distribution variable lamp 110. The controller 130 may be constituted by a digital processor, for example, a combination of a microcomputer including a CPU and a software program, or may be constituted by an FPGA (Field Programmable Gate Array), an ASIC (Application specific IC), or the like.

More specifically, when the vehicle having the lamp system 100 mounted thereon travels, the controller 130 controls the light distribution variable lamp 110 to draw a pattern for driving assistance on the road surface by the luminous flux BM. The type of the figure is not particularly limited, and for example, legal speed, road sign, and the like can be drawn so as to be easily seen by the driver. Alternatively, a graphic indicating the traveling direction of the host vehicle may be drawn to assist driving of another vehicle.

The high beam 104 may have a variable light distribution, similarly to the light distribution variable lamp 110. In this case, the controller 130 may also control the light distribution of the high beam 104 based on the camera image.

An ECU (Electronic Control Unit) 220 comprehensively controls the lamp system 100. Specifically, the low beam 102, the high beam 104, and the light distribution variable lamp 110 are instructed to turn on or off. In addition, information necessary for light distribution control is transmitted to the controller 130.

The controller 130 controls the light distribution variable lamp 110 in cooperation with the HUD system 210 to draw a pattern PTN on the road surface 900. The pattern PTN is not a mere illumination such as a low beam, but includes information to be presented to the driver or other traffic participants.

As shown in FIG. 1, the controller 130 may also be coupled to the HUD system 210 via a bus to directly cooperate therewith. Alternatively, a processor (ECU)220 as a master may be interposed between the controller 130 and the HUD system 210, and the controller 130 and the HUD system 210 may indirectly cooperate with each other.

The above is the configuration of vehicle 200 including lamp system 100. For a driver who is looking ahead of the vehicle during driving, the road surface 900 may have a shorter movement distance of the line of sight and a smaller movement of the focus than the HUD. According to the lamp system 100 of fig. 1, the HUD system 210 cooperates with the road surface drawing, and thus information can be reliably transmitted to the driver.

Next, the cooperation of the luminaire system 100 and the HUD system 210 is explained.

In one embodiment, the controller 130 of the light fixture system 100 traces the pattern PTN when it is presumed that the information displayed on the HUD212 is not being communicated to the driver, or is being ignored. The "information is not transmitted to the driver or is ignored" may be estimated based on the fact that the driver does not perform an action corresponding to the information. Conversely, in a situation where it is estimated that information is transmitted to the driver, information relating to the information displayed on the HUD212 is not drawn on the road surface. If a pattern cooperating with the HUD is drawn all the time on the road surface, the pattern is buried, and the degree of warning the driver to notice is relatively reduced. Therefore, by drawing the cooperative pattern on the road surface only in a necessary situation, the attention of the pattern drawn on the road surface can be enhanced.

For example, the controller 214 displays the limit speed on the HUD 212. The speed limit to be displayed may be obtained from a car navigation system or from an image in which a logo is captured. When the limit speed is displayed on the HUD212, it can be said that a state in which the limit speed is greatly exceeded (or a state in which the limit speed is greatly fallen below) is highly likely to cause no transmission of information or to be overlooked.

The road surface depiction by the luminaire system 100 is specifically described based on several embodiments.

(example 1)

Fig. 2 is a diagram illustrating an operation of the lamp system 100. The limit speed is set to 40 km. Fig. 2 shows the HUD screen and the pattern drawn on the road surface when the actual vehicle speeds are 40km/h, 50km/h, and 60 km/h.

A graphic (or character string) representing the speed limit is displayed on the HUD. When the excess (or deficiency) of the actual vehicle speed to the speed limit exceeds the allowable range (here, 20km/h), a graph of the speed limit is highlighted. In this example, inversion and non-inversion are alternately repeated.

The pattern depicted on the road surface may include information that emphasizes the information displayed on the HUD212 (speed limit), and/or warnings related to the information displayed on the heads-up display. As described above, the information on the information displayed on the HUD212 is not always drawn on the road surface, and the pattern on the HUD212 is not drawn on the road surface in a situation where it is estimated that the information is transmitted to the driver (i.e., a situation where the driver is following a speed limit, and the excess or deficiency is within the allowable range). In this case, a pattern unrelated to the HUD212 (for example, a pattern for warning a pedestrian) or the like may be drawn.

If the excess amount of the speed exceeds the allowable range (in this example, the vehicle speed exceeds 60km/h), it is estimated that the information is not transmitted to the driver/disregarded. At this time, the controller 130 blinks the display pattern PTN on the road surface. The blinking display can further prompt the driver's attention. If the period of the blinking is set to about 2 to 5Hz, the driver can be effectively alerted. In the example of fig. 2, the depicted pattern PTN represents a limit speed. Alternatively, the pattern PTN may also include a graph representing the speed overshoot.

(example 2)

Fig. 3 (a) to 3 (c) are diagrams for explaining the operation of the lamp system 100. As shown in fig. 3 (a), when the camera detects a stop sign 902, a figure for prompting a stop is displayed on the HUD. At this stage, a pattern related to the temporary stop is not drawn on the road surface 900.

In fig. 3 (b), the driver continues traveling without noticing the display of the sign 902 and HUD212 for temporary stop.

Fig. 3 (c) shows a state in which if the vehicle continues to travel while maintaining this state, the temporary stop line may be exceeded. In this state, the lamp system 100 draws a predetermined pattern PTN on the road surface 900. In fig. 3 (c), the predetermined pattern PTN includes a figure (character string) indicating a temporary stop. For example, if the braking distance is longer than the distance L to the stop line 904, it may be determined that the temporary stop line may be exceeded. Alternatively, the predetermined pattern PTN may be drawn on condition that the driver does not step on the actuator (is not performing the operation for braking). Alternatively, the acceleration of the vehicle body may be monitored, and the pattern PTN may be drawn on the condition that the deceleration is small. Alternatively, the predetermined pattern PTN may be drawn simply when the distance L to the stop line is less than a predetermined threshold value.

Fig. 4 (a) and 4 (b) are diagrams showing an example of drawing of the predetermined pattern PTN. Fig. 4 (a) shows a case where the pattern PTN flickers at a predetermined cycle. Alternatively, as shown in fig. 4 (b), black-and-white inversion may be performed at a predetermined cycle. This can further alert the driver. The period can be set to 2-5 Hz.

(position of road surface drawing)

Fig. 5 (a) to 5 (c) are views explaining positions where road surfaces are drawn. Fig. 5 (a) to 5 (c) show the driver's field of view. In this example, information 216A for speed limitation and information 216B for warning of lane departure are displayed in the display area of the HUD 212.

In fig. 5 (a), the pattern PTN is drawn without taking the HUD212 into consideration. The pattern PTN of the road surface overlaps the display area of the HUD212 according to the viewpoint position of the driver, and it is difficult to see the pattern PTN of the road surface, and also difficult to see the HUD due to the pattern PTN of the road surface.

Therefore, as shown in fig. 5 (b), the controller 130 is configured to be able to adjust the drawing position of the pattern PTN in consideration of the HUD. The controller 130 draws the pattern PTN at a position not overlapping the display area of the HUD212 as viewed from the driver. Specifically, the drawing position of the pattern PTN is shifted to a distant position in front of the host vehicle.

The positional relationship of the pattern PTN seen by the driver and the display area of the HUD212 changes according to the viewpoint position of the driver. The viewpoint position of the driver differs depending on the height of the driver, the position of the seat, and the like. Therefore, the controller 130 is configured to be able to correct the drawing position of the pattern PTN in accordance with the setting of the driver.

The display of the HUD212 may be turned on and off at times by the driver, depending on the preference. As shown in fig. 5 (c), the position correction function of the road surface pattern PTN of the controller 130 may be disabled when the display of the HUD212 is off. In this case, the pattern PTN may be drawn at the same position as in fig. 5 (a) without correction regardless of the setting of the driver.

The pattern PTN drawn on the road surface includes information to be presented to the driver (hereinafter, referred to as "1 st information") and information to be presented to other traffic participants (hereinafter, referred to as "2 nd information"). The pattern including the 1 st information is referred to as a 1 st pattern PTN1, and the pattern including the 2 nd information is referred to as a 2 nd pattern PTN2, which are distinguished as necessary.

Since the 2 nd information is not required to be presented to the driver, the 2 nd pattern PTN2 may be overlapped with the display area of the HUD 212. Alternatively, the 2 nd pattern PTN2 may be drawn in a blind spot of the driver (the nearest in front of the vehicle), but if the 2 nd pattern PTN2 to be drawn in a blind spot is moved forward uniformly in accordance with the setting of each driver similarly to the 1 st pattern PTN1, the moved 2 nd pattern PTN2 may overlap with the display area of the HUD212 or enter the field of view without overlapping, causing a disturbance.

The pattern PTN may include a pattern (pattern 3 PTN3) to be drawn at a predetermined position with respect to the vehicle (for example, 4m ahead of the vehicle). The 3 rd pattern PTN3 should not move according to the setting of the driver.

Therefore, depending on the kind of pattern PTN drawn on the road surface, the pattern to be position-corrected in consideration of the display area of the HUD (mainly including the 1 st pattern PTN1) and the pattern not in this case (mainly including the 2 nd pattern PTN2 and the 3 rd pattern PTN3) are classified, and the correction of the drawing position may be performed only for the former, while the position of the latter is not changed.

Fig. 6 (a), 6 (b), 7 (a), and 7 (b) are diagrams for explaining control of the drawing position based on the type of pattern PTN. Fig. 6 (a) and 6 (b) show the field of view of the driver. In fig. 6 (a), as described above, the 1 st pattern PTN1 including the 1 st information to be presented to the driver is drawn on the road surface, and the position thereof is corrected so as not to overlap the display area of the HUD 212.

In fig. 6 (b), a 2 nd pattern PTN2 including 2 nd information to be presented to traffic participants other than the driver is depicted on the road surface. In this example, the 2 nd pattern PTN2 is arranged in the traveling direction and includes a plurality of bars extending in the vehicle width direction, respectively. This 2 nd pattern PTN2 may also be a warning for pedestrians. Since the pattern 2 PTN2 is not meaningful to the driver of the vehicle, it may overlap the display area of the HUD212, and therefore, the position adjustment according to the setting of the driver is not performed.

Fig. 7 (a) and 7 (b) show a vehicle as viewed from above. Fig. 7 (a) corresponds to fig. 6 (a). To avoid overlap with the HUD212, a pattern PTN1 that should be presented to the driver is depicted in front of the vehicle 910. The dashed-dotted line 912 indicates a reference position from which the movement distance y can be adjusted by the driver.

Fig. 7 (b) corresponds to fig. 6 (b). Since the 2 nd pattern PTN2 does not need to avoid overlapping with the HUD212, it is drawn closer to the own vehicle 910 than the 1 st pattern PTN 1. However, the pattern 2 PTN2 may be drawn at a position substantially distant from the host vehicle, and as a result, may not overlap the HUD212, but the same point is true in that the position correction based on the setting of the driver is not performed.

Fig. 8 is a flowchart of control regarding the drawing position of the pattern. The flowchart does not limit the execution order of the plurality of processes shown, and the execution order may be changed within a range that does not hinder the processes, or several processes may be executed in parallel.

Before the start of traveling, the driver inputs setting information of the drawing position of the 1 st pattern PTN1 (S100). For example, an automobile draws a reference pattern for alignment on a road surface. The driver moves to a position not overlapping with the display area of the HUD212 by moving it back and forth (or left and right) with the user interface, and determines it. The position (or the amount of movement) of the reference pattern at this time is held in the controller 130 as setting data.

Next, it is determined whether or not the display of the HUD212 is valid (S102). When the display of the HUD212 is invalid (no in S102), the setting data is ignored and the drawing position is not corrected (S108).

If the display of the HUD212 is valid (yes at S102), it is determined whether or not the pattern to be drawn is the 1 st pattern PTN1 including the 1 st information to be presented to the driver (S104). If the pattern is the 1 st pattern PTN1 (yes in S104), the drawing position is corrected based on the setting data acquired in the processing S100 (S106), and the pattern PTN1 is drawn at the corrected position (S110).

In the determination process S104, when it is determined that the 2 nd pattern PTN2 is present (no in S104), the position correction for drawing is not performed (S108), and the 2 nd pattern PTN2 is drawn on the road surface (S110). The above is a description about the correction of the drawing position.

Next, a configuration example of the lamp system 100 is explained. Fig. 9 (a) and 9 (b) are diagrams showing a configuration example of the lamp system 100. In fig. 9 (a), the light distribution variable lamp 110 is incorporated in the headlamp 300A together with the low beam 102 and the high beam 104.

In fig. 9 (B), the light distribution variable lamp 110 is incorporated in a lamp 300B independent from the headlight 230. The lamp 300B is mounted on, for example, a bumper 240 in front of the vehicle 200.

Fig. 10 (a) and 10 (b) are diagrams showing configuration examples of a control system of a lighting system. The light distribution variable lamp 110 includes a DMD112 and its driver 114, and a projection lens 116. In fig. 10 (a), the light distribution pattern of the light distribution variable lamp 110 is generated by the ECU250 on the vehicle side outside the lamp 300A (300B). Therefore, in this example, the function of the controller 130 of fig. 1 is configured in the ECU250, and the ECU250 controls the light distribution variable lamp 110 in cooperation with the HUD system 210 or the ECU220 of fig. 1.

In fig. 10 (B), a lamp 300A (300B) is provided with a lamp ECU310, and the lamp ECU310 is configured with the function of the controller 130. The lamp ECU310 controls the light distribution variable lamp 110 in cooperation with the HUD system 210 or the ECU 220.

The present invention has been described above based on the embodiments. It should be understood by those skilled in the art that this embodiment is merely an example, various modifications are possible in combination of the respective constituent elements and the respective processing steps, and such modifications are also included in the scope of the present invention. Hereinafter, such a modification will be described.

(modification 1)

The light distribution variable lamp 110 may be incorporated in each of the left and right headlamps 300A and the lamp 300B. In this case, the irradiation regions of the left and right light distribution variable lamps 110 may be different. For example, the right half (or the front half) of the irradiation region may be irradiated by one light distribution variable lamp 110, and the left half (or the lower half) of the irradiation region may be irradiated by the other light distribution variable lamp 110.

(modification 2)

In the embodiment, the light distribution variable lamp 110 is an additional light source to the low beam 102 and the high beam 104, but the function of at least one of the low beam 102 and the high beam 104 may be integrated into the light distribution variable lamp 110.

(modification 3)

The lamp system 100 may have a mode in which the display of the HUD is stopped when the light distribution variable lamp 110 draws a pattern on the road surface. In addition, an interface (e.g., a switch) for the driver to select the mode may be provided on the vehicle.

The present invention has been described based on the embodiments using specific terms, but the embodiments only show one side of the principle and application of the present invention, and the embodiments allow many modifications of the embodiments and changes of the arrangement without departing from the scope of the idea of the present invention defined in the claims.
